COMPRESSOR FOR FLIERS.

Specification of Letters Patent No. 9,865, dated July 19, 1853.

To all whom it may concern:

Be it known that we, WILLIAM H. THOMPSON and RICHARD H. PLUMMER, of Biddeford, in the county of York and State of Maine, have invented a new and useful Improvement in Compressors for Fliers, by which improvement the compressor is adapted to the speeder flier and to work on a bobbin having two heads; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of the said drawings Figure 1, denotes a top view, Fig. 2, a front elevation, and Fig. 8, a rear elevation of one of our im proved compressors.

As compressors have been used on fly frames, they have been of necessity made of such width as to render them unapplicable to the flier of a speeder, and the double headed bobbin thereof. The large hole required to be made through them and for the roving to pass through with the freedom necessary to insure its draft, without being stretched or broken, has caused the compressor to be of too great a width to be used between the heads of a speeder bobbin, as when made so wide the bobbin could not be filled, without such contact of the compressor with the heads, as would be destructive or very injurious to it or the bobbin.

In order to enable us to apply the compressor to the double headed bobbin, we make it where the roving passes through it not only thicker, but narrower than it is usually made for fly frame fliers, and we make a hole a, through it, of much smaller diameter than the hole necessary to it when used on the flier of the fly frame. We next form a groove or channel 6, in the front edge of the compressor and leading into the hole a, as seen in Fig. 2. Out of such hole and in the rear edge of the compressor, and extending from the opposite side of the hole, we form another groove 0. We also make an opening (Z, down from the top of the compressor into the hole a, and nearly at a right angle with the grooves Z), 0, or passage made by them such opening being to enable an attendant or person to readily slip the roving sidewise into the hole (6, instead of inserting it endwise, through it, while its angular position with respect to the passages 12, 0, prevents the thread from slipping out of them.

In order to compensate for the strength lost by cutting the passage (Z, we increase the width of the compressor underneath the hole a, by a projection or rib e, which rib also serves as a guard to prevent the roving from doubling under the compressor and thereby being injured or broken.

By means of the small hole and the guide grooves leading into and out of it, we cause the roving to be kept close to the coil or layer on the bobbin, and much closer than can be effected when using the large hole compressors, as used on the fly frame. Besides this we are enabled to so reduce the width of the compressor, as to enable us to employ it on the speeder bobbins.

By our improvement we have been able to wind two and a half times as much roving on the speeder bobbin, as can be wound thereon in the ordinary way. We thus gain one hundred and fifty per cent. of wind 011 each bobbin.

o claim v The combination of the guard rib c with the hole a, and the passage Z2, and the opening (Z, substantially in manner and for the purposes as specified.

In testimony whereof we have hereto set our signatures, this third day of January A. I). 1853.
